The medical term used for underarms excessive sweating is axillary hyperhidrosis. This area of body has the highest concentrations of sweat glands as compared to the rest of the body. Most people naturally sweat higher in this area during any kind of physical activity (like exercising or walking) and also in hot climatic conditions.
The sweat producing apocrine glands are located in this area which is particularly efficient in producing oily and thick kind of sweat as compared to other body areas. The sweat is high in protein concentration that is why it leaves noticeable stain rings around the armpits area on the clothing.
People who suffer from axillary hyperhidrosis have overactive apocrine glands causing an abnormal production of sweat. This kind of hyperhidrosis starts at an early age and cause stress and anxiety among the young sufferers who start refraining from social interactions. Like most of other kinds of hyperhidrosis, excessive sweating in underarms can also be a result of hereditary factor or emotional factors.
The major downside of excessive underarms sweating is its unpleasant odour which further adds to the discomfort, anxiety and stress that is associated with this condition. The sweat in actual that is secreted by the sweat glands is odourless and human nose can barely smell it. but when this sweat interacts with bacteria on the skin it creates a bad undesirable odour that is called “Bromhidrosis”.
Unluckily, for those suffering from axillary hyperhidorsis, this condition is uncontrollable despite of using heavy deodorants or anti-perspirants the bad odour remain as apocrine glands don’t stop excreting sweat. So in order to gain control over this unwanted and unpleasant side effect, it is recommended for sufferers to wash their armpits regularly with anti-bacterial soap to turn away this inevitable reaction.
Like with other types of hyperhidrosis, the use of anti-perspirants and deodorants is considered to be on the go cure for axillary hyperhidrosis. These are usually available over the counter and are the starting point towards its control. If they fail to give the desired outcomes, then the next step is to move towards prescription-strength anti-perspirants which may cause more irritation to the skin.
If even prescription anti-perspirant products fail to give any relief from the excessive underarms sweating then Botox treatment for hyperhidrosis can be considered which give highly effective results in a single treatment. According to the results of a clinical study conducted on patients of axillary hyperhidrosis, almost 81% of the participants gained more than 50% decrease in their excessive sweating and almost 50% of the participants got relieved from the condition for 201 days after receiving the botox injections (Naumann M, Lowe NJ (on behalf of the BOTOX Hyperhidrosis Clinical Study Group). Botulinum toxin type A in treatment of bilateral primary axillary hyperhidrosis: randomised, parallel group, double blind, placebo controlled trial. BMJ 2001; 323: 5969.)
Another clinical study showed that Botox proved to be a safe and effective treatment for sufferers of axillary hyperhidrosis (Naumann, M.K., Hamm, H., Lowe, N.J. and ON BEHALF OF THE BOTOX® HYPERHIDROSIS CLINICAL STUDY GROUP (2002), Effect of botulinum toxin type A on quality of life measures in patients with excessive axillary sweating: a randomized controlled trial.
